Description
J. E. MORDEN DOOR LOCK Jan. 12, 1937.
Filed March 14, 1935 Patented Jan. 12, 1937 UNITED STATES DOOR LOCK Application March 14, 1935, Serial No. 10,991
1 Claim.
The principal object of this invention is to provide a simple but efficient form of locking device, which may be readily applied to either side of the door jamb to co-operate with the opening side edge of the door, and to provide a form of device which will not normally require cutting or recessing into the woodwork.
The principal feature of the invention resides in the novel construction of a plate element for attachment to the door jamb or the like, and having a pivotally and slidably displaceable looking bar member, which will automatically assume a locking position when swung into locking relation with the door.
In the drawing, Figure l is a perspective view of a door frame and door showing my improved device applied thereto.
Figure 2 is an enlarged perspective View of my locking device showing the locking element in the retracted or non-locking position.
Figure 3 is a view similar to Figure 2 showing the locking element swung to its locking position, and interlocked with the plate element.
Figure 4 is an enlarged sectional plan showing the device in a non-locking position and the relation of same to the door frame and door.
Figure 5 is a view similar to Figure 4 showing the locking element in locking relation to the door.
It is frequently desirable to provide a locking device for doors or swinging windows, which can be readily attached, and which will effectively lock the door or window against opening, and in such a manner that the locking member can not be tampered with from the opposite side of the door or window.
The present invention achieves these desirable features in a very simple manner, and in the preferred embodiment of my invention, I provide a plate I of metal, having a thickened body portion having a longitudinal slot 2 extending therethrough, and intersected by a transverse slot 3 forming with the slot 2 a T-shaped opening or recess. A thinner portion 4 of the plate I extends beyond the shoulder formation 5, and is adapted to flatly abut the inner face of a door jamb or window frame A, with the shoulder portion 5 abutting the corner extremity of the frame, and the portion 4 preferably has its inner end formed to present a laterally turned sharpened extremity 6, which will readily penetrate the wood frame or door jamb to retain the device in place, and a fastening screw 1 may be threaded through the bevelled hole 8, so that the device will be very securely held in position.
A mounting pin 9 is secured in the element I preferably by being threaded thereinto, so that it extends transversely of the slot 2, and arranged longitudinally of the slot 3, and intermediate of the width thereof. A locking bolt I0 is pivotally mounted at one end on the pin 9, and as shown in Figure 2, this locking bolt, when in its unlocked position, is adapted to be accommodated within the longitudinal slot 2.
When it is desired to move the locking bolt I0 to its locking position, the latter is swung outwardly on the pin 9 until it registers with the slot 3, and since the bolt It is also slidable on the pin 9, it will drop down into the lowermost end of the slot 3 to the position shown in Figures 3 and 5, where it will be positively locked against swinging movement by reason of its engagement with the walls of the slot 3. In this position it will form positive obstruction against the opening of door or window B.
A device such as described will be particularly suitable for application to doors where no other provision for locking the same is provided, or may be used as an auxiliary lock in addition to the regular locking means, and may be used with equal facility on swinging windows of all kinds, and it will be noted that by extending the slot 3 to opposite sides of the slot 2, the device is thereby reversible, in that it may be applied without change to either side of a frame opening depending on the side to which the door or window is hinged.
The outer end of the slot 2 is preferably slightly beveled to engage the correspondingly beveled end II of the bolt it] with a slight jambing action when the bolt is swung into flush relation with the body portion I, as in Figures 2 and 4:, and the rear face of the body I adjacent the slot 2 is preferably recessed to accommodate a thumb or finger, and thereby facilitate the swinging of the locking bolt out of the slot 2.
In order to unlock the door or window, the bolt Ill is simply caused to' slide along the pin 9, until it registers with the slot 2 and is then swung into the slot, where it will be retained against accidental displacement by the slight jambing action referred to.
What I claim as my invention is:
A locking device, comprising a member adapted for attachment to the frame of a door or window and having a locking member pivotally mounted thereon to be swung into locking relation with the door or window, said attachment member being recessed to accommodate the pivotal locking member when the latter is in nonlocking relation with the door or window, said attachment member being recessed on the outward side to facilitate pressure contact of a thumb or finger with the locking member to swing the same from its recessed position.
